I don't mean to offend anyone but I hate phone cases.
I think the cases hide the nice original design of the phone and unless you have an otter box or some extreme HULK-like case, your screen will still crack and break and all the stuff you're trying to avoid by using the ugly case.
In other words, phone cases make your phone ugly.
I roll with my IP5 black and naked.
Tell me why you have a case on your phone.
EDIT: I do have a anti-glare screen protector
